For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] A snap groove of a wiring terminal in the present embodiment relates to the technical field of wiring terminal installation, and is provided with a groove body 100 for snapping the wiring terminal. A snap plate 220 is provided on the other side of the groove body 100 away from the wiring terminal, and is slidably snapped with the groove body 100. The snap plate 220 can open and close the connection between the wiring terminal and the outside world as needed, thereby protecting the wiring terminal from the influence of the external environment when not in operation.

[0031] See also Figures 1 to 5 In this embodiment, a snap groove of a terminal block is used to encapsulate the terminal block, and includes a groove body 100 and a packaging assembly 200. The groove body 100 includes two clamping members 110 and a connecting member 120. The two ends of the connecting member 120 are respectively connected to the two clamping members 110 to form a first U-shaped structure 130. The terminal block can be firmly clamped in the first U-shaped structure 130 to ensure that the position of the terminal block is fixed to avoid loosening or displacement during connection and maintenance.

[0032] The connector 120 is provided with an opening 121, which is connected to the wiring terminal. The external circuit can be connected to the wiring terminal through the opening 121. The setting of the opening 121 reduces the area of ​​the wiring terminal exposed to the outside world and can also facilitate external sealing of the opening 121.

[0033] The packaging assembly 200 includes two snap fasteners 210 and a snap plate 220. The snap fasteners 210 are disposed on a side of the connector 120 away from the snap connector 110. Both ends of the connector 120 are respectively connected to the two snap fasteners 210 to form a second U-shaped structure 230. The snap plate 220 is slidably snapped into the second U-shaped structure 230, and the opening 121 can be opened and closed as needed to prevent dust and moisture in the external environment from entering the terminal block.

[0034] During use, usually, the buckle plate 220 is in a blocking state, completely covering the opening 121 to prevent dust and water vapor from entering the terminal area. When maintenance or inspection is required, the buckle plate 220 can be easily slid to open the opening 121 for easy operation.

[0035] In some embodiments, see Figure 3 The clip 210 includes a protrusion 211 and an extension 212. One end of the protrusion 211 is connected to the clip 110 and the extension 212 respectively. The protrusion 211 is arranged parallel to the clip 110, and the extension 212 is arranged relative to the other clip 210. The protrusion 211, the extension 212 and the connecting member 120 form a third U-shaped structure 240, which constitutes a closed space. The side of the clip plate 220 can be slidably clipped in this space. Since the third U-shaped structure 240 provides additional support, the clip plate 220 is more stable when closed and is not easy to fall off due to vibration or external force, thereby improving the reliability of the structure.

[0036] The third U-shaped structure 240 closely matches the side of the snap plate 220, thereby reducing the gap at the opening 121 and further improving the sealing effect, thereby more effectively preventing dust and water vapor from entering the terminal area and protecting the contact quality of the terminal.

[0037] In some embodiments, the spacing between the protrusions 211 of the two snap members 210 is consistent with the width of the snap plate 220, and the two sides of the snap plate 220 are respectively in contact with the protrusions 211 of the two snap members 210, which can limit the movement track of the snap plate 220, and the snap plate 220 is evenly stressed during the sliding process. Since the spacing is consistent with the width, the snap plate 220 can be firmly fixed after sliding into the snap member 210, reducing the risk of loosening or falling off. It can also improve the sealing strength between the snap plate 220 and the third U-shaped structure 240 to prevent the intrusion of dust and moisture.

[0038] When the distance between the protrusions 211 of the two clips 210 is greater than the width of the clip plate 220, there is a gap between the clip plate 220 and the protrusion 211, and the clip plate 220 may be offset or tilted relative to the protrusion 211, so that the clip plate 220 is unevenly stressed, affecting the smoothness and reliability of the sliding of the clip plate 220. At the same time, dust and water vapor may penetrate into the terminal through the gap, affecting the electrical performance of the terminal.

[0039] When the distance between the protrusions 211 of the two locking members 210 is smaller than the width of the locking plate 220 , the locking plate 220 cannot be inserted between the two protrusions 211 , and the corresponding function cannot be achieved.

[0040] In some embodiments, the extension 212 is arranged perpendicular to the protrusion 211, and the distance between the extension 212 and the connector 120 is consistent with the thickness of the snap plate 220. The snap plate 220 can be accurately clamped between the extension 212 and the connector 120, ensuring that there is no extra space when the snap plate 220 is in the snap-in position, avoiding looseness or shaking, and making the snap plate 220 firmly fixed. When the snap plate 220 is subjected to external force, the snap plate 220 will not be easily displaced or fall off, thereby ensuring the reliability of the packaging assembly 200 under various operating and environmental conditions.

[0041] Since the distance between the extension portion 212 and the connector 120 is consistent with the thickness of the snap plate 220, the snap plate 220 is firmly clamped, reducing the possible gap between the snap plate 220 and the extension portion 212 and the connector 120, which helps to improve the sealing effect of the entire packaging assembly 200 and effectively prevent the entry of dust, water vapor or other contaminants, thereby protecting the contact quality and safety of the terminal blocks.

[0042] In some embodiments, see Figure 4 A blocking portion 213 is provided at one end of the third U-shaped structure 240, and the blocking portion 213 is connected to the protruding portion 211, the extending portion 212 and the connecting piece 120. The existence of the blocking portion 213 effectively blocks the sliding range of the snap plate 220 in the third U-shaped structure 240, preventing it from sliding out from the side with the blocking portion 213 due to operational errors, vibrations or external impacts. The snap plate 220 can and can only slide out from the end of the third U-shaped structure 240 away from the blocking portion 213, which is convenient for operation and management, and greatly reduces the possibility of exposed terminal blocks in the electrical cabinet, thereby reducing safety accidents caused by poor contact or environmental factors.

[0043] The blocking portion 213 can also play an impact-resistant role. In particular, when the device is subjected to external impact, the blocking portion 213 can disperse or absorb part of the impact force, thereby protecting the buckle plate 220 from damage.

[0044] In some embodiments, see Figure 3 The two clamping parts 110 are arranged opposite to each other to form an "eight" structure for clamping the terminal. The terminal can be inserted into the "eight" structure. The two clamping parts 110 form a symmetrical and stable clamping area, so that the terminal can be accurately clamped and fixed, avoiding looseness caused by uneven force or loose fixation.

[0045] The "eight" structure is relatively symmetrical, and the force on the card contact can be evenly distributed on both sides of the terminal, reducing the situation where the force is too large on one side, thereby reducing the risk of deformation or damage of the terminal due to stress concentration.

[0046] The clamping area formed by the figure-eight structure can better seal the terminal block and reduce the contact surface between the terminal block and the external environment. This design can effectively prevent external factors such as dust and water vapor from invading the terminal block area, improving the overall sealing and protection effect.

[0047] By setting the "eight" structure, the terminal blocks can be easily inserted or removed, and users can quickly and accurately complete the installation and removal of the terminal blocks, which improves operational efficiency and convenience.

[0048] In some embodiments, the clamping member 110 is provided with a bent portion 111, and the bent portions 111 of the two clamping members 110 are arranged facing each other, and the bent portions 111 can effectively clamp the slot body 100 on the terminal. The bent portions 111 are arranged facing each other, forming a mechanical blocking structure to prevent the slot body 100 from coming off the terminal when subjected to external force, vibration or other interference.

[0049] The inflection portion 111 provides additional engagement force, forms a firm connection by contacting the slot body 100, and enhances the fixing force between the terminal block and the slot body 100. The slot body 100 is not easy to loosen or shift during long-term use, thereby improving the reliability and stability of the connection.

[0050] In some embodiments, see Figure 5 The opening 121 is a connecting hole, and the connecting hole is arranged in a one-to-one correspondence with the wiring hole of the wiring terminal, and an external straight plug can be inserted into the wiring hole of the wiring terminal through the connecting hole. The connecting hole is arranged in a one-to-one correspondence with the wiring hole of the wiring terminal, ensuring that the external wire or the connector 120 can be accurately inserted into the wiring hole of the wiring terminal, which can eliminate the deviation that may occur when the straight plug is aligned with the wiring hole, and improve the accuracy and reliability of the connection.

[0051] The precisely corresponding connecting holes ensure that the wires can accurately contact the wiring holes of the terminal blocks, reducing the problem of poor contact due to inaccurate alignment, improving the reliability of electrical connections, ensuring smooth conduction of current, and reducing the risk of failures or accidents caused by poor contact.

[0052] In some embodiments, see Figure 5 The plurality of openings 121 are arranged in an array along the length direction of the slot body 100. The plurality of openings 121 can be matched with a plurality of wiring terminals at the same time. The plurality of openings 121 arranged in an array allow the user to simultaneously connect a plurality of wiring terminals in one operation, which greatly improves the wiring efficiency. It is particularly suitable for complex electrical systems that need to connect a plurality of wires, which reduces the operation time of wiring one by one, making the entire installation process smoother and more efficient.

[0053] Workflow: First, multiple wiring terminals are installed in an array in the cabinet. Then, the first U-shaped structure 130 of the slot body 100 is clamped on the multiple wiring terminals so that the openings 121 are arranged one-to-one with the wiring holes of the connection terminals. Next, the snap plate 220 is inserted into the second U-shaped structure 230 so that the snap plate 220 can slide relative to the slot body 100 to open or close the opening 121, thereby protecting the wiring terminals from the influence of the external environment when not in operation.
